Nuclear fusion propulsion, offers 1,000 times more power than current ion thrusters, potentially enabling trips to destinations like Jupiter's moons and Alpha Centauri.
Nuclear rockets have the potential to drastically cut travel times to Mars. It could also allow for quicker return trips due to operations being carried out in time for Mars-Earth alignment.
Nuclear thermal rockets (NTRs) have been envisioned as a revolutionary propulsion technology since the 1950s, promising faster and more efficient by using nuclear reactors to heat liquid hydrogen and expel it through a nozzle, achieving much higher temperatures and speeds than chemical rockets.
The development of NTRs began with the US Air Force's Rover program in the 1950s and was advanced by NASA's NERVA program (1961-1973) and projects like Rover at Los Alamos National Laboratory. Manufacturing fuel rods and materials resistant to high temperatures and corrosive hydrogen remains a challenge. The Phoebus 2A, tested in 1968, was the most powerful space nuclear reactor ever built. It was not utilized due to its size, and cost.
